The Volo Race diving fins have a shovel length that varies from 33.5 to 39.5 cm depending on the size. The fins have a closed and anatomical foot pocket. Soft longitudinal inserts allow a controlled deformation of the blade while finning. The channel shape displaces more water, creating more thrust with the same effort. The muscle power is thus transformed into propulsive thrust.
The OPB system allows the blade to maintain an optimal angle throughout the finning cycle.
